but on the hive side, unless you set mapred.job.queue.name on the hive cli,
they will be
I notice that in some beginning texts on starting a Hadoop MapReduce job
sometimes JobClient/JobConf is used and sometimes Job/Configuration is used.
I have yet to see anyone comment on the features/benefits of either set of
methods. Could someone comment on their preferred method for starting a
Failed task can be because the task failed to report to JT or anything. Did

If not do you have further logs available?

want to hard code jobtracker or hdfs information in my code.
Maybe it's a bug in hadoop eclipse plugin?
Hi Folks,

Hi Bharati,
Your mapper class implementation methods have access to a MapContext:

This is a subclass of TaskAttemptContext:

The 'standard' way to do this is using queu-acls to enforce a particular user
to be able to submit jobs to a sub-set of queues and then let the user decide
which of that subset of queues he wishes to submit a job to.

Actually, if you care about being binary compatible b/w hadoop-1 and hadoop-2,
stay with old mapred API.

Hi Kevin,
JobClient/JobConf is the old mapred API and Job/Configuration is the
improved new API, so in general the latter is preferred.
